Difference Between Seamless and Welded Stainless Steel Pipe. How to Identify Whether a Pipe is Seamless or Welded?

Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.

In Seamless pipe, there are no welding or joints and is manufactured from solid round billets. The seamless pipe is finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 26 inch OD. Applicable in for High-pressure applications such as Hydrocarbon Industries & Refineries, Oil & Gas Exploration & Drilling, Oil & Gas Transportation and Air and Hydraulic cylinders, Bearings, Boilers, Automobiles, etc.

ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24” OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge. It is mainly used for low/ medium pressure applications such as transportation of water / oil. Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats and processing can be handled on site to customer specifications.

How to identify whether the pipe is seamless or welded?

If it is ASTM A53,

Type S means seamless.
Type F is furnace but welded,
Type E is Electrical resist welded.
That is how. It is the easiest way to identify whether pipe is Seamless or ERW.

What are the Various Grades of Stainless Steel, Metallica Deals in?

As one of the biggest stainless steel suppliers in India, we stock and supply all major grades of stainless steel.

Austenitic Stainless Steels

301

High strength for roll formed structural components

304, 304L, 304H

Standard 18/8 grades

310, 310S, 310H

High temperature resistant grades

316, 316L, 316H

Improved resistance to pitting corrosion in chloride environments

321, 321H, 347

Stabilized grades for heavy section welding and high temperature applications

904L

High resistance to general corrosion, pitting and stress corrosion cracking

Super duplex with very high resistance to pitting and stress corrosion

Martensitic Stainless Steels

410

Standard martensitic grade for low-duty hardened applications

416

Free-machining bar grade

420

Higher hardness martensitic grade for cutlery, cutting tools and dies

431

High hardness and toughness grade, primarily for shafting

440A, 440B, 440C

Very high hardness grades used in cutting tools

Precipitation Hardening Stainless Steel

630

(17-4PH) High strength shafting grade

What are the Maximum Operating Temperatures of Stainless Steel Grades?

Stainless steels have good strength and good resistance to corrosion and oxidation at elevated temperatures. Stainless steels are used at temperatures up to 1700° F for 304 and 316 and up to 2000 F for the high temperature stainless grade 309(S) and up to 2100° F for 310(S).

What is the Impact of Various Alloying Elements on the Properties of Stainless Steel?

Element

Effect on Stainless Steel

Chromium

Forms a passive film with oxygen that prevent the further diffusion of oxygen into the surface

Ties up carbon and prevents inter-granular corrosion in welded zone of ferritic grades

Nitrogen

Increase strength and corrosion resistance in austenitic and duplex grades

Silicon

Improves resistance to high temperature scaling

Sulfur

Usually kept low excet for “free-machining” grades

Carbon

Usually kept low. Used in martensitic grades to increase strength and hardness

What are the Steel Pipe Sizes?

Steel pipe sizes

Pipe size is quoted as a “Nominal Pipe Size” or NPS. The origin of the NPS numbers for smaller pipes (< NPS 12) is different to the origin for larger diameter pipes. However, all pipes of a specific NPS number have the same external or outer diameter (OD). The internal diameter will vary depending on the wall thickness of the metal. The reason for this is so that the same structural supports can be used for all piping of a specific NPS number regardless of the wall thickness.

Schedules

Steel pipe schedules are a way to describe the wall thickness of the pipe. This is a critical parameter as it is directly related to the strength of the pipe and the suitability for specific applications. A pipe schedule is a dimensionless number and is calculated based on the design formula for wall thickness, given the design pressure and allowable stress.

Examples of schedule numbers are as follows: 5, 5S, 10, 20, 30, 40, 50, 60, 80, 100, 120, 140, 160, STD, XS, and XXS—with the most common being schedules 40 and 80. As the schedule number increases, the wall thickness of the pipe increases. The schedule number of a pipe therefore defines the internal diameter, as the OD is fixed by the NPS number.

As one of the biggest stainless steel pipe stockholder and supplier in India, Metallica carries inventory of over 10,000 tons in its warehouses in Mumbai, Maharashtra India. We sell our stainless steel pipe products throughout India, and to international clients. We can supply our stainless steel tube products not only in industry-standard lengths and diameters, but also in custom length and diameters.

How are Steel Pipes Certified?

Certification of Steel Pipes

Manufacturers issue a Material Test Report or Mill Test Report to validate that the product meets the chemical analysis and mechanical properties specification. The MTR will contain all relevant data to the product and will accompany the product through its lifecycle.
